This study had two specific aims. The first aim was to investigate whether, during a silent reading task, persons who stutter encode phonological and semantic information move slowly then persons who do not stutter. The second aim was to investigate how the syntactic context of stimulus sentences influences the speed of coding. Fourteen adult persons who stutter and 14 adult persons who do not stutter participated in a self-paced word-by-word reading experiment. While reading a prose text silently, participants monitored target words that were specified before the presentation of the text. The target words to be monitored for were phonologically similar, categorically related, or identical to a cue word. The influence of syntactic information on the word-monitoring reaction time was studied by presenting the text either as normal prose, in a syntactically correct but semantically anomalous version, or in random word order. The results suggest that the two groups are not different with respect to the speed of word identification but that persons who stutter retrieve semantic information more slowly than persons who do not stutter.
本研究有两个具体目标。第一个目标是调查在默读任务期间，口吃者在对语音和语义信息进行编码时是否比非口吃者速度慢。第二个目标是研究刺激句子的句法上下文如何影响编码速度。14名成年口吃者和14名成年非口吃者参与了一项自定节奏的逐字阅读实验。在默读一篇散文文本时，参与者监测在文本呈现之前指定的目标单词。需要监测的目标单词在语音上相似、类别相关或与一个提示词相同。通过将文本呈现为正常散文、句法正确但语义异常的版本或随机单词顺序，研究句法信息对单词监测反应时间的影响。结果表明，两组在单词识别速度方面没有差异，但口吃者比非口吃者检索语义信息的速度更慢。
